A rocket slammed into the headquarters of the international peacekeeping force in Kabul, the Afghan capital, tonight. There were no reports of injuries.

The compound, consisting of several buildings surrounded by high stone walls, is across the street from the heavily fortified U.S. Embassy. Few peacekeepers were present when the rocket hit.

"At this point it appears that a building may have been damaged," said Lt. Col. Thomas Lobbering, a German peacekeeping spokesman.

A second rocket struck the eastern edge of the Afghan capital. There were no reports of injuries there, either.

A police spokesman said the rockets were fired from several miles east of Kabul.

The strikes were the latest in a series of attacks on foreign troops and aid workers in Afghanistan since the start of the war in Iraq, and Afghan government officials blamed them on remnants of the ousted Taliban militia.

Kabul is patrolled by nearly 5,000 peacekeepers, a 22-nation force under the command of Germany and the Netherlands. The Taliban was ousted in late 2001 by U.S.-backed opposition groups. Thousands of U.S. troops remain in the country, searching for remnants of the hard-line militia and al Qaeda.

Mohammed Azim, an Afghan soldier on duty outside the peacekeepers' compound, said the Defense Ministry issued a warning four days ago that suspected al Qaeda operatives had entered the city.

In the past week, a Red Cross worker and two U.S. Special Forces soldiers were killed in separate incidents in southern Afghanistan.
